It would be cool if we could produce a different message depending on which player scores the goal. For example, the "Jahwohl" narrow angle goals can be scored reliably with certain players, but if you score it with say, #7, that's a rather low probability so you may call that a "Lucky bastard goal". Similar could be scoring a lob with #2.

The keeper is trying to collect the "loose" ball. He calculates the interception point and runs to collect the ball at that spot.He doesn't bother checking if that interception point is somewhere off the pitch.I think the attacker can trigger this action by letting the ball roll slightly ahead of him while dribbling.
